Abstract
The utility model relates to an oil external circulation lubrication device of a hydroturbine bearing; the hydroturbine bearing is arranged on a bearing seat; the oil external circulation lubrication device comprises an oil pump, an oil cooler and a globe valve; one end of the oil pump is connected to the lower cavity of the bearing seat through a pipeline, and the other end of the oil pump is connected to the oil cooler through the pipeline; the oil cooler penetrates through a bearing upper cover through the pipeline and is connected to an oil shield; and the globe valve is arranged on the pipeline between the oil pump and the oil cooler. According to the oil external circulation lubrication device of the hydroturbine bearing, because the oil cooler is solely arranged outside the bearing to cool lubricating oil, the cooling power is improved, the load bearing capability of a bush is improved, and the scope of application of the bearing is expanded.
Description
Technical field
The utility model relates to a kind of auxiliary device of bearing, especially a kind of oily outer circulation lubricating fitting of water turbine bearing.
Background technique
The lubricated of various large-scale rotating machinerys is lubricant oil directly to be stored in rotate in the casing; During equipment work,, oily temperature rise, expand, overflow along with rotor rotates for a long time; Thereby cause the rotating machinery oil starvation; Therefore phenomenons such as bearing, bearing shell locking need constantly to inject new lubricant oil, to guarantee the proper functioning of equipment.Both bothered but constantly annotate new lubricant oil, be difficult to an amount of accurately injection again, and waste lubricant oil, inefficiency.
The existing lubricant type of cooling generally is to adopt the lingering remnants of past customs of cooled engine to come lubricant oil is cooled off, and this type of cooling is difficult to reach favorable cooling effect.The bad cooling effect of lubricant oil tends to cause that engine temperature rises, output power descends, serious meeting cause motor Bearing score, embrace fault such as cylinder, thereby influence the normal use of motor.
The model utility content
For overcoming the existing technology deficiency, the utility model provides a kind of oily outer circulation lubricating fitting of water turbine bearing.
A kind of oily outer circulation lubricating fitting of water turbine bearing; Said water turbine bearing is installed on the bearing support; Said oily outer circulation lubricating fitting comprises oil pump, oil cooler and stop valve, and oil pump one end is connected to the bearing support cavity of resorption through pipeline, and the oil pump the other end is connected to oil cooler through pipeline; Oil cooler passes bearing upper cover through pipeline and is connected to the oil cover, and the pipeline between oil pump and the oil cooler is provided with stop valve.
Preferably, a side of described oil cooler is provided with water intake, and opposite side is provided with water outlet.
The utility model is provided with oil cooler separately lubricant oil is cooled off outside bearing, improved cooling power, has increased the bearing capacity of bearing shell, has enlarged the using scope of bearing.
Description of drawings
Fig. 1 is the workflow schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but the protection domain of the utility model is not limited to this.
With reference to Fig. 1, a kind of oily outer circulation lubricating fitting of water turbine bearing, said water turbine bearing is installed on the bearing support; Said oily outer circulation lubricating fitting comprises oil pump 1, oil cooler 2 and stop valve 3; Oil pump 1 one ends are connected to bearing support cavity of resorption 4 through pipeline, and oil pump 1 the other end is connected to oil cooler 2 through pipeline, and oil cooler 2 passes bearing upper cover 5 through pipeline and is connected to oil cover 6; Pipeline between oil pump 1 and the oil cooler 2 is provided with stop valve 3, through stop valve 3 adjustment oil inlet quantities.
One side of oil cooler 2 is provided with water intake 8, and opposite side is provided with water outlet 9.
During use, extract the deep fat of bearing support cavity of resorption 4 out through oil pump 1, deep fat gets in the oil cooler 2 through pipeline, through stop valve 3 adjustment oil inlet quantities.Along with the turnover of oil cooler 2 current, the heat of deep fat is taken away, reach the lubricant oil cooling purpose, be delivered to oil to cooled cold oil through pipeline then and cover 6 oilhole, be re-introduced into bearing shell 7 working surfaces and be lubricated.
